BLADE-3s Are Different
Wheatstone BLADE-3s have a lot in common with the set of IP Audio products that form the basic I/O building blocks of an AoIP network. But there’s a whole lot more going on inside a BLADE-3 than mere I/O. There’s a powerful CPU complete with operating system to provide the routing, logic, and audio power to practically create a self-contained production studio.
When they are networked, their power is virtually unlimited.
We have BLADEs for just about every purpose, all of which can be networked together with our control surfaces and accessories to make one smart WheatNet-IP audio network.
Inside a BLADE-3
When we invented modern broadcast audio networking, we vowed to build the first truly intelligent IP audio system. One where every interface held the DNA of the entire system for recovery. A system with true Gigabit connectivity. One that required only a single CAT-6 cable to interface any network piece – to carry audio AND control information. A system that could actually be up 24/7/365 and handle everything you need, an actual 'station in a box', yet so simple to interface as to be virtually foolproof.

I/O BLADE-3s
I/O BLADEs are far more than mere access units connecting studios, elements and Wheatstone control surfaces in the WheatNet-IP Intelligent Network. Yes, I/O BLADEs convert audio and logic inputs to data streams on the network and convert outgoing data streams to hardware outputs. But these 1RU I/O units – which come in analog, digital and analog/digital versions – also have intelligence inside. Each I/O BLADE comes with a CPU and operating system so you can do amazing things with your audio network, from routable mixing and logic-follow-audio to a whole lot more.
Connect automation and production PC’s, codecs, audio processors, controllers, and other devices directly to the network without installing specialized sound cards, A/D-D/A converters, audio wiring, or control connections. The I/O BLADE communicates at the speed of Gigabit Ethernet connectivity for optimum network QoS and reliability.
Each individual I/O BLADE can hold the brain trust of the entire system’s operation for exceptional network redundancy and scalability. Smart and independent, all BLADEs know what they’re supposed to do — and what every other BLADE is supposed to do.

Logic Follows Audio Wherever It Goes
Mixers and Audio Processing Included
The I/O BLADE-3s’ internal mixers are full-featured, stereo mixers implemented within its internal hardware. The inputs and output busses of these mixers are available as resources on the network, accessible anywhere and don’t use up any of the inputs or outputs of the BLADE-3 itself. From simple features like summing, splitting, and level adjustment all the way to creating custom mixes and intercom systems under automatic control and performing fades and segues, the potential uses for these mixers are nearly endless. The I/O BLADE-3 includes the Wheatstone ACI (Automation Control Interface) “tool box” for third party control of its functions, such as routing, ducking, panning, logic control, mixing and silence detection. Each I/O BLADE-3 supports up to 20 ACI connections that can be used with devices like Talent Stations, GP panels and SideBoard surfaces as well as to integrate with automation systems and other Wheatstone partners' gear for control purposes.
Interoperable and Flexible

Silence Detection, Emergency Audio
Easy to Configure and Maintain, with Failsafe Activating the I/O BLADE-3 is as easy as plugging it in. No need to assign it an IP address or prioritize packets. Once plugged in, it will instantly recognize that it’s been connected to a functioning network and configure itself into that network with almost no intervention at all! All of its resources are instantly available so it can be pushing out or bringing in audio in little more than a minute after it is first plugged in.

I/O BLADE-3s come with dual OLED displays for monitoring and control of most functions right from the front panel, including audio routing setup, monitoring, network information, alarm status, enabling and operating utility mixes, setting input and output gain, and connecting audio processing. Settings can also be done remotely using a PC. Ongoing changes and updates are just as easy. Change a signal name on the fly and it is instantly updated in every device on the network; no reboots or configuration file gymnastics required. The I/O BLADE-3s Aliases feature allows the same source to be identified by different names. A signal can be given an alias that’s more familiar to a particular operator, and multiple aliases can be used so different operators can share logic functions, source feeds and routing while using signal names they recognize.

Console Audio BLADE-3s provide audio I/O and DSP mix engine functions for WheatNet-IP radio control surfaces (see Gibraltar Mix Engine for TV Consoles) through the network switch.
Unique to Wheatstone’s console engine approach is its true IP connectivity. The control surface connects directly into the network switch itself, giving it access to mix engine functions as well as direct access to automation systems, network applications and other control surfaces that make true system interoperability possible.
The IP88CB Console Audio BLADE-3 comes standard with L-8, L-12, E-1, IP-12 and IP-16 control surfaces. A single Console Audio BLADE-3 is all that is needed for some studio operations, but busy studios often require an additional I/O BLADE-3 or Wheatstone’s CB32 model which doubles the amount of I/O in 2RU.
All Console Audio BLADEs are AES67 compatible to bring audio from other AES67-compatible devices and signals into and out of the WheatNet-IP Intelligent Network.
Mix Engine BLADE-3s
Mix Engine BLADEs are required for all Wheatstone IP consoles and are available in specific configurations for each. Console Audio BLADEs (see above) combine I/O and Mix Engine for our smaller consols for use in compact installations where extensive I/O is not required. For mid to larger installations, the mix engine is either included with the console or purchased separately, allowing you to tailor the I/O to your specific requirements.

A Mix Engine BLADE-3 houses all the DSP processing power for an individual radio control surface (see Gibraltar Mix Engine for TV Consoles) and distributes the four stereo PGM buses, four stereo AUX sends, per-channel mix-minus feeds, monitor outputs, and other bus signals to the network. Once on the network, bus signals are available as sources and destinations anywhere. This creates an extremely flexible system in which program outputs from one surface can be sources on any other surface; for example, a news mixer’s program bus can be brought up as a source on the air studio surface. While the IP88E doesn’t house audio I/O, it does include 12 universal logic (GPIO) ports for interfacing various external switches, indicators and devices for control purposes.
They are AES67 compatible for use with other AES67-compatible devices and signals in the WheatNet-IP Intelligent Network.

Network EDGE is designed specifically as a translator between high-quality, low-latency studio networks such as WheatNet-IP and low-bandwidth STL connectivity options such as IP radios.
Typically located at the studio, the Network EDGE interfaces directly to an IP wireless radio or commercial leased line for point-to-point connectivity between locations. Network EDGE can be used with any of the major IP radio brands currently on the market. When used within the WheatNet-IP system, with a Network EDGE at one end and a BLADE at the other, this opens up a world of possibilities based on BLADE I/O functionality such as silence detection, clip player, logic for automation, et al.
The Network EDGE includes local I/O (two AES and two stereo analog) and 12 programmable logic ports.
EDGE provides the data buffering needed between the studio IP audio network and the STL in order to handle the latency swings typical of unlicensed IP radios. It handles the necessary delay as a buffer to any latency shifts that come across the link and acts as an interface between the WheatNet-IP audio network and the IP radio.
This is because the critical difference between unlicensed and licensed wireless IP systems is how the two handle latency. IP wireless radios operating on licensed frequencies have exclusive use of the band and therefore have a consistent, lower latency, typically around 100 microseconds. Comparatively, latency on an unlicensed system can jump from 2 milliseconds up to 12 or 20 milliseconds depending on interference or even changes in weather patterns.

Processing BLADE-3s
Network processing has proven a popular, efficient, and very cost effective way to apply audio tailoring to a lot of applications in different studios from a single 1RU box located anywhere in your network.
Our M4IP-USB is a four-channel mic/voice processing BLADE-3 that's in use in more broadcast studios than any other processor today.
And our Aura8-IP BLADE-3 provides eight individual stereo processors you can deploy anywhere on your network to, for example, sweeten phone calls, process streams, improve remote audio quality, make your satellite feeds sound great, process headphones, and on and on.
The Power of BLADES
BLADEFEST 2018 Puts BLADEs Through Extreme Tests
Would any sensible broadcast engineer put his/her system through dozens of consecutive reboots? Would she/he ever send audio on a purposefully Rube Goldberg-ish route? Would they use new, unproven switches? That’d be asking for trouble, right?
But we did. As we prepared to roll out a major revision of our BLADE software, we put together a huge WheatNet-IP system: 12 radio and TV consoles, 62 hardware BLADEs, 100 software BLADEs, talent stations, SideBoards, Smart Switch panels, and software including three different vendors’ automation systems. Then we added in AES67 devices from Genelec, Ward-Beck, Dante, and Axia. All of this was tied together by new models of Cisco and Dell switches.
Then we routed audio from one device to the next until our signal path passed in a big daisy chain through every single piece of gear. Just cabling and configuring the system took days! Then, with our engineers monitoring closely, we ran the system through a series of automated torture tests that included completely rebooting the system and verifying proper operation afterward. We’re proud to say that after more than 160 reboots, not a single connection failure or loss of audio occurred.
We did all this so you won’t have to. When you take that inevitable catastrophic power hit, you can be confident that your WheatNet-IP system will come back up healthy and ready to pick up where it left off.
BLADEFEST 2016
Our first BLADEFEST was held in 2016 and was just as impressive. It was documented by Scott Johnson with a photo essay and a short video. For an indepth look, READ THE STORY
Cool Stuff BLADE-3s & WheatNet-IP Can Do
BLADE-3s can do things that mere I/O nodes can’t because of their embedded CPU and OS that make routable utilities such as audio mixing and processing possible. But what does that mean to you? For starters, it means faster, better and easier ways of doing broadcast. Here are some practical ways you can put BLADE-3s to use in your station. Grab a refreshing beverage - there's a lot to take in here.
Audio Routing and Control
Route any audio input to any output or all outputs. Send one GPI to multiple GPOs or marry GPIOs to an audio source and have them follow that source through the system. All BLADEs in the network live on a simple crosspoint matrix.
Auto Mono Summing
BLADEs have the onboard processing and intelligence to auto sum and level match a stereo output that is routed to a mono output or destination. If, for example, you want to feed a stereo console bus down a hybrid or codec, the audio will be available in both mono and stereo on the receiving end. If you route a mono source such as field recording device or remote interview through the router it will put that mono source on both channels.
Left: The above shows a mono source being routed to both stereo and mono destinations in a BLADE-3. (Two dots indicate a stereo or dual channel connection. A single dot indicates it's a mono to mono connection.)
Right: The above shows a stereo source being routed to mono destinations.
Input Gain Control
Calibrate levels for each source or destination using bargraph metering. Shown, audio levels for the individual channels color coded over a 40dB range, with the highest level being “+20” VU, corresponding to +24dBu, 0dBFS, and the onset of clipping. These meters show the actual input signal level as modified by the input gain setting. The bouncing bar at the top shows the peak audio level while the solid column shows the short-term average audio level using VU time constants. Adjusting source levels ensures that they have enough volume to keep noise levels low in comparison, but not so high that they overload the equipment and cause distortion.
Output Gain Control
Destination gain adjustments are useful for output signals known to be too low or too hot, such as those feeding headphones or amplified speakers with no gain control of their own, to bring them to the correct listening level. As shown, the audio gain of individual output channels can be adjusted over a range of +/-18dB in .1dB steps. The nominal setting is 0, corresponding to an output level of +4dBu analog, or -20dBFS digital, providing for 20dB of headroom.
Mixers for Mic Groupings, Talkback, etc.
Each I/O BLADE contains two stereo 8x2 internal mixers that become a source or input to the system. This can be useful for grouping several mics to a single output. You can use the output of each mixer as a talkback source.
Mixers for Panning Mic and Caller Feeds
The BLADE-3's two stereo 8x2 internal mixers are independent of each other, so they can feed audio to each other or another BLADE-3. The output of mixer #1 can be brought up on a fader in mixer #2, for example. With balance control on each fader, this can be useful for recording a telephone mix with the “callers” on the left channel and the “announcers” on the right channel. The output of the mixer feeds the recording device.
Automation Mix-Down
The BLADE's stereo 8X2 internal mixers can be used to mix down multiple channels to a single output. Shown is a BLADE utility mixer being used to mix down multiple RCS automation channels to a stereo output, which can then be programmed as the automatic failover source in an emergency. This is also useful as a way to bypass the studio, so that with the push of a button or a command from the automation system, this output can feed the transmitter and free up the on-air studio for production or voice tracking, for example.
Automation Interface. One Cable.
One cable is all it takes to integrate your automation system with a network of BLADEs. WheatNet-IP audio drivers replace expensive sound cards, GPIO cards and external switches.
Unlimited Salvos or Macros
Each I/O BLADE can store hundreds of customized salvos, which can be useful for assigning feeds to codecs or hybrids and switching between studios. Group any audio source, logic and destination together that can be triggered by event or time.
Quick Source and Destination Changes
Each BLADE can act as an X-Y controller sending any system source or input to any of its outputs. This comes in handy when changing feeds to monitors, codecs, hybrids or recording devices.
Logic on RJ45 Connectors
Each I/O BLADE is equipped with 12 logic ports on RJ45 connectors, which can be individually designated during set up as inputs or outputs for interfacing to various external switches and indicators. Logic ports can output to closures for machine control, on-air lights, mic tallies, transmitter remote control and the like. They can also receive closures from external devices like satellite closures, remote mic panels or triggers from your automation system for channel ON/OFF.
Selectable Master Clock
Automation PCs and other digital devices that require a specific sample rate are no problem. I/O BLADE-3s provide system clock rates selectable at 44.1kHz or 48kHz, External Reference or AES67. While all AES inputs in I/O BLADE-3s are equipped with sample rate converters, the master clock sets the sample rate of all of the system’s AES digital outputs.
Monitor Devices with SNMP (Simple Network Management Protocol)
BLADEs include SNMP agent software for centralized monitoring of all BLADEs in a large distributed network. You can configure alarms and set thresholds in order to be notified should a problem occur and therefore respond with quick corrective actions through e-mail, SMS, traps and executing custom scripts. SNMP is part of the internet protocol suite defined by the Internet Engineering Task Force (IETF). Network management systems use SNMP to monitor network-attached devices such as BLADEs for conditions that may require action by the end user.
Share Resources, Connections
Create a predetermined back haul, IFB feed or mix-minus for each device based on its location in the network or on a fader. For shared resources like a codec, I/O BLADE-3 software will ‘automagically’ give the proper return feed to the codec based on its destination. So, if you pull up the codec in Studio One, the mix-minus from Studio One will automatically and magically be routed to the return feed. Later, when you call up the same codec on the console in Studio Two, the Studio Two mix-minus will be routed to that Codec. This is useful for call-ins and live talk shows that require a separate mix-minus
Routable Audio Processing
I/O BLADE-3s include a multiband processor useful for processing incoming audio from callers, remotes, codecs, satellite feeds and microphones. You can also use it to process output audio for headphones, web streams, pre-processors, IFB, or for level protection for STL applications. This is a routable processor that includes 4-band parametric equalizer, 3-way crossover, 3 compressors, 3 limiters, and final look-ahead limiter.
Silence Detection and Failover
Every single audio output channel can be programmed with silence detection and automatic switchover function. Showing on the left is the console PGM channel being routed to the station transmitter during normal operation. On the right shows a failover state after silence was detected.
Video: Complete System Reboot
Here's an idea of how powerful BLADEs and WheatNet-IP are...
In this video, we have a large, 82-BLADE/15-LXE system set up that we are testing inside and out. The goal – try and break it. Jay Tyler takes this gigantic system completely offline to see how long it takes to reset itself. Spoiler – it takes 80 seconds!
Additional BLADE Applications & Configurations
Here are just a few unique uses, configurations and applications for our BLADE access units that our customers have told us about. If you have a unique BLADE application, we'd like to hear from you. Drop us an email and let us know!
BLADE as an A/D and D/A Converter
With a single IP88AD I/O BLADE, you can easily convert from analog to digital audio
BLADE as an Audio Snake
Use BLADEs to transport audio between the on-air or production studio and a performance studio using CAT6, wireless link or optical fiber. Carry the mic and direct feeds from the stage area to the network. Do separate mixes using the BLADE’s 8x2 stereo mixers, or capture multitrack recordings that could be saved for future mixing projects (such as the CD or DVD release). All this can be done without the need for a conventional audio snake with transformer splits for the various feeds.
BLADE Plus IP Meters App = Failover Monitoring
You can wire your sources to the inputs of the BLADE 3 and then using the WheatNet-IP’s meter app, build a meter screen to monitor all of the sources and destinations in the system. If silence is detected, the BLADE will failover and the particular meter will change color to give you a visual notification. Each time a failover is detected on an output, a logic signal is generated that can be routed to any logic port in the system.
BLADEs as Distribution Amplifiers
Analog BLADE as a 1x8 distribution amplifier
Analog BLADE as a 2x4 distribution amplifier
BLADE as Mixer
With two built-in 8x2 stereo utility mixers, the BLADE has more flexibility than some hardware solutions.
BLADE as Part of an IP STL
Network EDGE is designed specifically as a translator between high-quality, low-latency studio networks such as WheatNet-IP and low-bandwidth STL connectivity options such as IP wireless radios.
IP wireless radios in the unlicensed 5 or 24 GHz range are priced from a few hundred to several thousand dollars. Typically located at the studio, the Network EDGE interfaces directly to an IP wireless radio or commercial leased line for point-to-point connectivity between locations. Network EDGE can be used with any of the major IP radio brands currently on the market. When used within the WheatNet-IP system, with a Network EDGE at one end and a BLADE at the other, this opens up a world of possibilities based on BLADE I/O functionality such as silence detection, clip player, logic for automation, et al. The Network EDGE is AES67 compatible, and includes local I/O (two AES and two stereo analog) and 12 programmable logic ports.
